THIS PART IS LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND IS NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE. California law defines a "racing vehicle" as "a competition vehicle not used on public highways." (Calif. Health & Safety Code 39048) This part may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event. Competition-only motor vehicles may not be driven to a racing event on a public highway and must be transported on a trailer or other carrier. USE OF THIS PART IN ANY OTHER VEHICLE MAY SUBJECT YOU TO FINES AND PENALTIES FOR VIOLATION OF FEDERAL AND/OR STATE LAW, WILL VOID YOUR WARRANTY FROM BURGER MOTORSPORTS, INC, AND CAN VOID YOUR VEHICLE'S WARRANTY. It is your responsibility to comply with all applicable federal and state laws relating to use of this part, and Burger Motorsports, Inc hereby disclaims any liability resulting from the failure to use this part in compliance with all applicable federal and state laws.

By default the JB4 ships on map1. For higher boost map, logging, firmware updates, and other features, you'll need a JB4 Mobile adapter for wireless connection to your phone or a BMS data cable for wired connection to a laptop.

Map guide as of v15+ firmware (selected via JB4 Mobile/laptop interface. Map1 is the default map)

Map 0: JB4 disabled
Map 1: 4psi over stock peak tapering to 2.5psi at high RPM. Default performance map suitable for all 91+ octane fuels.
Map 2: 5psi over stock tapering to 4psi at high RPM. Suggested for 93+ octane fuel.
Map 3: 6psi stock tapering to 5psi at high RPM. Suggested for high quality fuel including unleaded race gas, ethanol mixtures up to 30%, or high quality octane booster like Torco or Boostane.
Map 4: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%.
Map 5: Up to 7psi over stock but without top end taper. For unleaded race fuel use and bolt on modifications. May not be suitable for E85 mixtures due to high fuel pressure dropping. If using this map on E85 you should be experienced at reading your own logs and evaluating ignition advance and fuel pressure.
Map 6: User adjustable map. Enter value of boost over stock by RPM on user adjustment page.
Map 7: Progressive WMI (water/meth) map. Increases boost as a function of methanol flow & methanol boost additive. Holds boost low until WMI is flowing to avoid tip-in knock, and reduces boost as a function of WMI flow in the event of interruption like running out of fluid, leak, or component failure.
Map 8: Valet map, runs around half as much boost as stock.

Firmware Updates:

Download using the new JB4 Mobile firmware database or externally by clicking this link.

JB4 User Adjustment Settings as of v15 firmware:

Boost by gear: Enter amount of boost reduction in 1st, 2nd, or 3rd gear. Very useful for improving traction on RWD vehicles. We generally run 5psi in 1st, 1psi in 2nd, on our GT on stock tires to avoid wheel spin during launch mode. This reduces boost in 1st gear by 5psi, and reduces boost in 2nd gear by 1psi. You can reduce boost below factory levels as needed.

Fuel Bias: Used to fine tune fuel control if you disable the preset mapping using option bit1. Not suggested for most. Once enabled a value of 140 will target 14:1, 120 will target 12:1, 13.2 will target 13.2:1, etc. Note you won't exactly hit the target so you'll need to datalog and evaluate. Going too rich will result in fuel pressure drops and stuttering, and going too lean may result in increased knock activity.

Map6 Boost: Allows you to enter a customized boost profile. You'll enter only peak boost over stock here, so 6.0 means add a maximum of 6psi over stock, at that RPM point. The JB4 will blend this request with pedal input, engine temperatures, etc, to provide a smooth mapping. Generally this is only used for advanced customers who are able to read their logs and looking to make a map less aggressive than our off the shelf maps.

Optional EWG connectors and setup for improved boost targeting: Stinger 3.3L EWG Connectors - N54Tech.com - International Turbo Racing Discussion

Options (formerly FUD) settings as of v14 firmware:

bit0 - Turn on to disable JB4 fuel control or if optional fuel wires are not installed.
bit1 - Turn on to enable manual fuel control adjustment by RPM. Generally not suggested unless advised by a tuner. See firmware notes for how adjustment is entered.
bit2 - Turn on to disable JB4 hot/cold water & oil temperature protection
bit3 - Turn on for slow speed CANbus, useful for some older models.
bit4 - Turn on to disable JB4 over boost, run lean, and fuel pressure safety systems.
bit5 - Disable EWG connectors if installed.
bit6 - Turn on if vehicle has an aftermarket flash map loaded to the ECU.
bit7 - Turn on to run more linear (sluggish) gas pedal to boost mapping.

FutureUseA (FUA) as of v22 firmware:

FUA 1: Show cyl 2-6 as raw timing rather than timing corrections.
FUA 2: Required for 2018 and earlier 1.6L models
FUA 3: Required for 2019+ 1.6L models

LagFix BETA (DWP) as of v22 firmware:

Added in v22 and newer firmware this feature is used to boost pedal response and reduce turbo lag during routine driving. LagFix is enabled using the (mislabeled) DWP setting on the JB4 user adjustment page. A value of 0 disables the feature. A value of 100 is the "maximum effect". Most report values of 60-80 feel best behind the wheel so feel free to play around and see what works for your specific driving style.

Spark Plugs:

Only map1 has a chance of working well with the factory plug gap. For the 3.3L we suggest closing the gap on the stock plugs to 0.024", or replacing the stock plugs with Denso 5346 plugs and gapping them to 0.022". For the 2L and other motors we suggest HKS plugs gapped 0.022" to 0.026".

For your convenience you can order the required 3.3L plugs, gapping tool, and magnetic socket from BMS as a discounted package: https://www.burgertuning.com/collect...iri-spark-plug

3.5T JB4 Development and testing: Kia 3.5L JB4 Development - N54Tech.com - International Turbo Racing Discussion

Fuel Control Wires:

These add on wires attach to the JB4 harness and your vehicles sensors to give the JB4 the ability to directly change the air/fuel ratio. The factory tuning runs in the 10:1 range and leaning that out to 11.5:1 has proven to be worth significant power at higher engine speed. Note these are preinstalled on the JB4 harness now so only need to be attached to the o2 sensor signal wire to enable using the included posi-taps or optional harness adapters.

No JB4 setting changes are needed to enable the fuel control wires.

Forward video to 4min for systems already equipped with fuel wires to see how to attach them.

For 3.3L they attach to the o2 sensor signal RED wire. For those using the optional PNP adapters the 3.3L signal wire is also RED for your convenience.

For 2L applications only the longer wire is used and it goes to the primary o2 sensor signal WHITE wire. For those using our PNP adapter it's the black wire in position #2

For 1.6L applications only the longer wire is used and it goes to the primary o2 sensor BLUE wire. There is minimal tuning benefit on the 1.6L models so for now we only suggest connecting them if you plan to run E85 mixtures or WMI. If using our PNP adapter it's the red wire.

JB4 Mobile / Blue Tooth attachment:

Note newer systems have the blue wire built in to the harness. If your blue tooth adapter does not have a spare/loose blue wire and instead has that blue wire pinned in to the JB4 connector then all you need to do is attach the blue tooth adapter to the JB4 control board. Skip the posi-tap directions as those only apply to older models with a loose blue wire.
